Summary/Abstract: Since June of 1804, one of the goals in Serbia’s war plans has been to liberate most of the Eyalet of Bosnia, which resulted in 10 years of a war campaign on the Drina River. Until the summer of 1806, there were no significant developments in that region. The 1806 attack on Belgrade by the insurgent army prompted the Bosnian vizier Husref Mehmed Pasha to send 3,000 soldiers across the Drina River where they have been badly defeated in the battle on the Mišar hill near the town of Šabac. However, the great success of the insurgent army could not change the situation between the two opposing sides. In the years to come, both Karađorđe's and the Turkish army crossed the Drina River on several occasions, but neither of them had successful campaigns. The Turkish response to the Serbian offensive in the spring of 1809 was the counteroffensive that started in the summer of the same year, which was the start of the final clash with Serbia from 1812 to 1815. As the military activities on the Drina River intensified, the Turkish army in the Eyalet of Bosnia mobilized up to 80,000 army men in preparation for the final campaign against the insurgent forces in Serbia. In September of 1813, the Turkish army won the victory in the decisive battle and left the territory from the Drina River to Belgrade completely clear of the insurgents for the following two years.
